Hi, my LG LD2120WH dishwasher stopped working recently because of the detergent container being empty and the salt level too low. After replacing these the machine still doesnt want to start washing. The timer displays fine but doesnt count down either and the machine turns off after a couple of minutes. Please help.

Please check at both ends of the drain hose and confirm that you do nit have a leak. Also, please confirm that water is not leaking directly under the dishwasher.
If you are certain that you do not have a real leak, check the impeller (under the mesh filter in the sump area beneath the lower dish rack) is not damaged and is firmly in place.
The E1 error code is a Leakage Error, detected by the motor spinning faster than it should if the unit is filled with water.
Please report back with what you find. Good Luck!

try unblocking the inlet hose under the machine.. My machine was overflowing inlet water into the tray under the machine setting off the above mentioned aquastopper switch. I removed side pannel, then one end of the inlet hose under the machine and dragged a wire with cloth tied to end through, removing a serious amount of built up scum. no more overflowing!!

A lot of dishwashers do not have salt dispensers. If it does, the salt is added to a container which has a lid on the base (floor) on the inside under the bottom basket. Unscrew the lid and add the salt. Use normal pool salt. It is the same as "special dishwasher salt" that you pay a lot for. When full, the salt will last for 12 to 18 months. Most machines that have a salt container, also have a warning light on the panel to let you know it needs refilling. Dishwasher tablets do not add salt to the machine. Make sure you wipe up any salt that you may have spilt on the base of the machine, it will stain or rust the cabinet.

The top light is apparently to indicate that the salt (!) has run out.

The bottom light is apparently to indicate that rinse aid has run out.

For the record, that seems to be a Zanussi DE-6854 dishwasher, and I found the manual here: (link)

"Special salt can be added in one of two ways: 1) If you are using dishwasher detergent that already contains salt, the detergent including the salt is placed in the detergent compartment. - In this case the water softener must manually be set to 1 and electronically to 1 to ensure that the special salt is taken from the detergent container only. 2) If you are using dishwasher detergent and salt separately, the special salt is to be put into the salt container. - In this case the water softener must manually be set to 1 or 2 and electronically between 1 and 5 (depending on the water hardness in your area) to ensure that the special salt is taken from the salt container only. Only use salt specifically designed for use in dishwashers. All other types of salt not specifically designed for use in a dishwasher, especially table salt, will damage the water softener. Only fill with salt just before starting one of the washing programmes. This will prevent any grains of salt or salty water, which may have been spilt, remaining on the bottom of the machine for any period of time, which may cause corrosion." (Page 6)

"Only use branded rinse aid for dishwashers. Never fill the rinse aid dispenser with any other substances (e.g. dishwasher cleaning agent, liquid detergent). This would damage the appliance." (Page 7)

The manual also explains how to turn the Rinse Aid light off permanently if you do not wish to use rinse aid.

Check the following:- The Salt Container - Found at the bottom of the Dishwasher. (If required, replenish salt)- The spray arms (They usually get clogged at the small holes where the water should spray out of)- Us less heat (High heat can leave white visible stains on glass)

This could simply be a detergent problem, but is most likely due to a low salt level in the water softener. The salt is used by the water-softener to prevent hard-water deposits which result in white stains on crockery and glasses. There are several things which can cause this:

1. There is no salt in the salt container.
2. The lid on the salt container isn't screwed on properly. (Don't overtighten though!)
3. Water softener is set too low

If you've checked and topped up the salt level and the lid is screwed on fully, then your water softener may be set too low. You should consult your user manual / installation instructions to change the setting.

The white deposits can also be caused by the rinse-agent being set too low. On your washer, the adjustment will be on a dial under the flap where you refill the rinse agent. I think it's numbered 1-5, so if it's set on 1, try number 3, if it's on 3, try 4 or 5. You may have to adjust a couple of times until you get it right.

If this doesn't solve the problem, try changing your detergent. Check the packaging and if your using phosphate-free detergent, try one containing phosphates. Phosphate-free is more eco-friendly though!

How is the water hardness in your area. If my watersoftener is low on salt I get this problem. Also you could try a rinsing agent in the little spot beside the dish washing detergent. Some detergents I find also leave a film. I find Cascade works the best.

Well Dishwasher salt is a particular grade of sodium chloride salt, and is used for recharging the built-in ion-exchange resins of the water softener in dishwashers that have a built-in water softener. The salt particles are larger than the size of table salt particles, and dissolves slowly enough that it will not clog the softener unit. This salt does not have added iodide salts, and it should have minimal amounts of iron and manganese salts. Some dishwasher detergents are marketed as not needing dishwasher salts. These detergents use higher levels of phosphate that increases the solubility of hard water ions. Never use table salt or detergent in the salt compartment of your dishwasher as this will damage your water softener unit. You can purchase the dishwasher salt from the below link -

hi friend,HOW TO GET THE BEST FROM YOUR DISHWASHER
Always follow the manufacturer's instructions and read the directions carefully on detergent, rinse aid and salt packaging.
Cleaning your machine about once a month will remove any grease and lime scale deposits which can build up on the inside of the machine. Special dishwasher cleaning detergents are available which are used when the machine is empty. These cleaners will often leave a fresh smell in the dishwasher too. If you want to have that fresh smell all the time, use a dishwasher freshener. These are usually supplied as hanging tags, which should be carefully positioned away from any moving arms. A freshener is essential if you load during the day and then run the machine at night. -->WHAT ELSE CAN I DO TO GET THE MOST FROM MY DISHWASHER?

These items can be washed in a dishwasher, with the following guidelines:Glassware - Any ordinary glassware and ovenware such as Pyrex. Do not wash lead crystal glasses unless they carry a "dishwasher safe" label.Tableware - Most everyday crockery is safe. Bone china usually has under-glaze decoration and should be safe. Avoid antique or hand-painted and over-glaze decorated items. If in doubt, check with the manufacturer.Cutlery - Stainless steel and silver cutlery are normally suitable for machine washing, but it pays to rinse off any acidic food before loading to prevent any corrosion and, if possible remove the cutlery immediately after the cycle, to avoid prolonged exposure in a humid atmosphere. Do not mix steel and silver cutlery in the same basket and wash bone or wooden-handled items by hand.Plastics - Check whether they are dishwasher safe and do not place in the lower rack, where the heating element may affect the plastic during drying.Pans - Stainless steel is ideal for dishwashers. aluminium can be washed in the machine, but may discolour during the rinsing. If in doubt, remove aluminium pans before the rinse cycle.
Always wash cast iron and wooden handled items by handWHY DOES MY MACHINE HAVE A WATER SOFTENER?
If the water is soft (i.e. does not contain calcium particles), the detergent will work more effectively and there will be less streaking on dishes. Hard water can also block the washer jets with lime scale and cause deposits on heating elements, which will reduce the cleaning efficiency, increase electricity costs and shorten the life of the machine. All dishwasher manufacturers (Bosch, Miele, Siemens) and detergent suppliers want you to get the best results from the machine - and soft water is one of the most important factors in achieving this. The way to ensure water remains soft is to regularly top up the reservoir with granular salt. Three in one salt tablets do not activate the water softener.HOW MUCH SALT DO I NEED TO ADD?
Your machine may have a float indicator or a warning light to tell you when salt needs adding to the water softener. Often float indicators are difficult to see, and there is no accurate guide as to how much salt you need to add. Quite simply, just add granular salt to the reservoir until it won't take any more!

The softener will use the salt to replenish itself each time you wash. As an approximate guide, you should do a full top up about once a month. If your machine doesn't have a warning light, a good way to remember to check and / or top up is to do it on a regular day of the month (e.g. the first Saturday or the 15th)CAN I USE ORDINARY TABLE SALT?
No. Table, cooking, rock and sea salts may contain additives that can actually increase water hardness. Also, the fine consistency of some of these salts mean they are likely to clog when wet. Always use granular dishwasher salt because it is very pure and is the right consistency for use in your machine.
Granular salt is the ONLY type of salt that should be used to regenerate the softener. Be aware that some varieties of ‘dishwasher salt’ use Dead Sea salt. This variety may contain minute insoluble organic matter that may adversely affect the resin within your softener over time. If you are in doubt about the origins of the salt, ask the retailer or manufacturer.WHAT DETERGENT SHOULD I USE?
All modern dishwasher detergents are formulated to work specifically in dishwashers. On no occasion should ordinary washing up liquid be used, as it will cause excess foam, which can result in a leak. If it is accidentally used, sprinkle ordinary salt into the chamber to disperse the resulting suds. Then rinse away the excess salt before using.
There are 3 main types of dishwasher detergent - Powder, liquid or gel and tablets. Which one you choose will be down to personal preference, but most people find tablets very convenient, although using powder is usually more economical and liquids are less abrasive on more delicate items.WHAT IS RINSE AID?
Rinse Aid is added to a special compartment in the machine and a very small amount is released during the final hot rinse cycle, to reduce the formation of water droplets on crockery etc and so ensures that the water dries away properly and evenly to avoid leaving smears.
Dual action detergent usually contains rinse aid, which is released at a different rate to the cleaning agent and so helps reduce smearing etc without the need to add separate rinse aid. Some 3-in-1 tablets contain an ingredient, which has a 'salt action', which also helps to improve cleaning, but NOTE this is not a substitute for adding salt to the water softener.

The salt action takes place in the cleaning chamber of the machine, but does not actually replenish the water softener. Research has shown that whilst 3-in-1 detergents do cleandishes effectively, their performance is improved by adding salt to the water softener reservoir.
As the performance of machines can vary, as can local water conditions, it is always best to follow your manufacturer’s advice. Some manufacturers advise that if you have unsatisfactory cleaning performance eg white powder residue, poor drying or dirty dishes, then you should return to using three separate products ie detergent, rinse aid and granular salt. Be aware that if you have not been filling the salt reservoir and relying on the salt in 3-in-1 tablets, then it may take a few cycles to re-generate the softener.
hope this helps u
please rate me..................
thank u for using fixya

Get an aqua vac and suck out the water (with the dissolved detergent)from the salt container. Refill it with water and repeat the process couple of times.
Fill the container with water and salt and it should be fine.
Good luck !!
